- Accurately describe the overwater wind field during storms (including fine-scale
variations) in order to assess the importance of wind-induced currents and waves in
initiating and maintaining resuspension events.
- Address the question as to whether resuspension events represent a response to
the aggregate effects of a season of individual storm events or an episodic response
to a single large storm event.
- Configure mesoscale meteorological model for realtime and hindcast simulations of
- For specific resuspension events, generate hindcast "control" simulations that
well reproduce the observed meteorological and lake circulations;
- Test response to fine-scale storm details by providing meteorological data during
resuspension at 6 km grid spacing;
- Place resuspension events into historical context, by investigating (with Dave
Schwab) the meteorological and oceanographic aspects of prior events.
- Clear evidence from frequency and magnitude of resuspension events during field
program that they are an episodic response to storm events;
- Fine-scale features, such as the wind vortex of 11 March 1998, play a role in
lake circulation and the transport of resuspended sediment;
- Mesoscale model data provide improved input to hydrodynamic models
